%N Maximal consecutive determinant of n X n persymmetric matrix with entries {-1,0,+1}.

%C A persymmetric (or Hankel) matrix has M[ i,j ] = M[ i-k,j+k ] for all i and j (matrix is constant along antidiagonals).

%C Interpretation: largest m such that for each d for which 0 <= d <= m a matrix with determinant d exists. - _Bert Dobbelaere_, Jan 26 2019
